Question: : A similarity between electromagnetic waves and matter waves?
----------------------------------------------------------------------------------------------------------------
Answer: electromagnetic waves are the combination of electric field and magnetic field and the matter wave related to dicrete particles. They are both waves (obviously), and both are made of particles which obey the equation E = hf. Where E is the energy of a particle and f is its frequency. Matter waves can move at varying speeds, and matter waves can be at rest. EM waves always move at c in vacuum.

Answer is 1500 m/s
Wave speed = Frequency x wavelength
500.0 x 3.00 = 1500 m/s
Answer:
214.72m
Explanation:
The range (R) of a projectile can be calculated using the formula:
R = u²sin2θ/g
Where R = Horizontal range
u = initial velocity
θ = angle of initial velocity
g = acceleration due to gravity (9.8m/s²)
According to the provided information in this question, R= ?, u= 51m/s, θ = 63°, g = 9.8m/s².
Hence, R = u²sin2θ/g
R = 51² × sin 2×63/ 9.8
R = 2601 × sin 126/9.8
R = 2601 × 0.809/9.8
R = 2104.25/9.8
R = 214.72m
Answer:
ΔV = -2.1 L
Explanation:
To solve this exercise we can use the ideal gas equation for two points
PV = nRT
P₁V₁ = P₂ V₂
where point 1 is on the surface and point 2 is at the desired depth,
V₂ = 
let's calculate
V₂ = ( 
) 3.5 L
V₂ = 1.4 L
this is the new volume, the change in volume is
ΔV = V₂ -V₁
ΔV = 1.4-3.5
ΔV = -2.1 L
When you say "Which...", does that mean you're looking at a list of choices
and not sharing it ?
To change (kilometers/hour) to (meters/minute), multiply (kilometers/hour) by
(1,000 meters/kilometer) x (hour/60 minutes).
Both of those fractions are equal to ' 1 ', so the process doesn't change the
original quantity, just its units.
